Trying to figure out how to hook up new h/u to my factory bose. Got all the specs

Alright I drive a 1991 Acura Legend LS with a broken h/u. It is equipped with a bose headunit, 80x4W Peak Power Bose Amp(made by kicker) behind the rear seat, 6.75 front speakers, and 6x9 rear speakers. The speakers function at a 2 ohm load per channel.

Not sure what would sound better? Running my factory speakers off of the aftermarket h/u or using a LLC (Line Level Converter) in between the h/u and bose amp. What would I connect my stock amp to the h/u with?

Thanks in advance! Any help is greatly appreciated. Driving around with no music is killing me

If you can find a harness adaptor for the car then you can run thru the factory amp. Otherwise I would get rid of all the factor stuff and replace with new amps and speakers. If your budget is tight, Start looking for the harness.
